Fasteners are components that help in joining one or more fixtures in the system. Duplex Screws are fasteners that are designed with a helical ridge of male threads that align to a tapered hub having female threads. The Duplex Stainless Steel Screws showcase superior corrosion and oxidation resistance properties in different conditions. The self-threading screws are designed in different shapes and configurations. Duplex Machine Screws are devices that are smaller than an average screw having thin and accurate threads. These screws range in sizes up to 19.05mm and more. The Duplex Hex Screw is designed with a hexagonal cross-section. The six-sided screw can easily fasten with wood, metal, etc. The versatile Duplex Hex-head Screw allows for improving the tightening torque in the system. These screws offer an economic option and can be easily inserted with a simple key. A Duplex Head Screw has a socket that can be shaped in the form of a button or hexagonal configuration. These screws securely hold the components to correct specifications. The A276 Gr 2205 Set Screws are employed in strongly securing an object by applying pressure and friction against another fixture. These screws are utilized without a nut. UNS S31803 Screws are available in different sizes and shapes to meet customer requirements.

The Duplex Wood Screws are strong screws that bind wooden objects. These screws don’t damage the integrity of the wood and are very affordable. Alloy 2205 Concrete Screws offer a convenient and easy way to fasten concrete. These screws don’t require any hammering, anchoring or shielding to install them. The ASTM A276 Type 2205 Receptacle Screws are robust fasteners that effectively hold outlet boxes and receptacles to existing construction easily. RemoveRite Duplex Screws are quality-assured and produced with the best raw materials and latest technology by our renowned technicians.
